Opps, heres the solder side.

Anyone interested in the PCB pattern? Let me know and Ill post it as PDF

Oooh that's nice. What did you use to lay that out with? Also, did you fab that yourself or did you have it done at a PCB house?

Dam that nice and clean.
If you could, please post the pdf of the PCB.

If you have a Digikey or Mouser quick order list that would help people to get one of these together fairly quickly.

Thanks Rando, that is one part I forgot to ask.

I used Protel DXP for the layout.

Laser printed on a transparencies, exposed the board on UV, develop it, etch and drilled it, all done at home.

By the way rando, do you have any problem when debugging?

I get this error > "ICD0083: Target not in debug mode, unable to perform operation" when stepping, seems ok when running though.

Ill post the PCB layout soon, need to dig out the PDF converter software first.

thats a sweet looking board,

do you use actual UV lamps or just blacklights?

i'm currently putting together a exposure unit using 3 blacklights, so I can use it with plan paper instead of buying those damn expensive transparencies

Here are the PDFs, I just added a thanks to Lothar Stolz on the composite drawing.

The components dimension are based on what I have laying around. The capacitors may be alittle tricky as they tend to varies in pitch/spacing legs. The rest of the components are standard in sizes.

Parts I added >

D3 = 1N4000 (polarity protection)
LED1 = 3mm LED (power indicator)
R17 = 330 ohms (current limit for LED1)
R18 = 330 ohms (current limit for VPP)
C11 = 470uF 16V electrolytic (smoothing capacitor)

The rest of the components should follow the correct desginator as described on the website.

I used UV exposure unit.

You can use normal paper, soak it in oil after printing the layout. Increase the exposure time to about 50%.

On transparencies I exposed the board for about 8-10 mins. On normal oil soaked paper I increase it to about 12-15 mins.

Just make sure the toner is on the same side as the copper. You will need to print in mirror image.
